OS X Mountain Lion: Notification Center on Mountain Lion is a a great place to keep track of all your notifications, but we're still waiting for the notification app Growl to update to support Mountain Lion. While we're waiting, Mountain Growl is a free app that pushes Growl data to Notification Center, but still manages to retain full Growl support.

We've mentioned another app that does this, Hiss, before, but Mountain Growl does does things a little differently. Both apps push Growl data to Notification Center, but Mountain Growl also keeps full Growl support. This means if you use remote notifications, or Prowl, you can still continue to use them in Mountain Lion. You also get a lot more control over which notifications you see. If you've been dissatisfied with Hiss, or you just want to check out another option while you're waiting for an official Growl update, Mountain Growl is worth a look.
